Chapter 5 Installation
These are the same cables that are used with all P330 family modules.
To connect stacked switches:
Note: When adding a module to an existing stack, first connect the stacking cables
and then power up the module.
1 Plug the light grey connector of the Short Octaplane cable into the port marked
"to upper unit" of the bottom Avaya P330 switch.
2 Plug dark grey connector of same Short Octaplane cable to the port marked "to
lower unit" in the unit above. The connections are illustrated in Figure 5.3.
3 Repeat Steps 1 and 2 until you reach the top switch in the stack.
4 If you wish to implement stack redundancy, use the Redundant Cable to
connect the port marked "to lower unit" on the bottom switch to the port
marked "to upper unit" on the top switch of the stack.
5 Power up the added modules.
Caution: Do not cross-connect two Avaya P330 switches with two Octaplane (light-
colored) cables. If you wish to cross-connect for redundancy, use one light-colored
Octaplane cable and one black redundancy cable. Figure 5.2 shows an incorrect
connection.
Note: You can build a stack of up to 10 Avaya P330 switches. If you do not wish to
stack all the switches in a single rack, use long Octaplane cables to connect two
physical stacks as shown in Figure 5.3.
